GEORGE KAIBUEECK, OF JERSEY CITY, NEW JERSEY.

VENTILATOR.

Application filed September 28, 1908.

To all whom "it may concern:

Be it known that I, GEORGE KABUREGK, a citizen of the United States of America, and residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Ventilators, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to ventilation and the object thereof is to provide means for producing this result through the frames of windows, doors, and the like; a further object being to provide means, within a building provided with my invention, for regulating the degree of said ventilation; a still further object being to provide automatic closure devices for the said ventilating means in the event of fire within or without the building and, with these and other objects in mind, my invention consists of the construction hereinafter fully described and claimed.

My invention is fully described in the following specification, of which the accompanying drawings form a part, in which the separate parts are designated by the same reference characters in each of the views, and in which Figure 1 is a partial sectional view through a window constructed according to my invention, taken on the line 1-1 of Fig. 2; Fig. 2 is a partial elevation thereof on the interior of the building; and Fig. 3 is a partial section thereof, taken on the line 3-3 of Fig. 1.

In the drawings forming a part of this application, I have shown a window provided with a frame a composed of sheet metal but which may also be composed of wood or the like, and which is provided with the usual sash runs a and a and with a recess or chamber a thereover, opening outwardly and partially closed by means of louvers a outwardly of which is placed a deflector plate a to prevent drafts, and beneath the louvers is an inclined plate a bent to form a gutter which is provided with holes a for the passage of water, and the chamber a also communicates with the interior of the building by means of an opening a preferably arranged over the inner or lower sash run.

Pivotally mounted adjacent to the louvers a is a shutter 72 which is normally held in Specification of Letters Patent.

Patented Feb. 15, 1910.

Serial No. 454,965.

the raised position shown by means of a rod 6 connected therewith by means of any suitable fusible material 6 adapted to be melted at a predetermined temperature, said rod being also held to the uppermost louver in the same manner by means of fusible material 6*, and the shutter I), when released by the melting of the said fusible material, drops into the position indicated by dotted lines, against the plate 07, a weight Z2 being provided to insure this movement, and when in this position, the shutter b closes all communication between the chamber a and the outer air, as will be seen.

Similarly mounted above the opening a is a shutter 0, provided with a weight c to insure downward movement thereof and set at an angle, when raised, to permit this movement, but being held in the raised position by means of a rod or plate connected, by means of fusible material 0*, to a shaft 0 rotatable in a sleeve 0 connected with a support 0 therefor, said shaft rotation being accomplished by means of a double arm cl secured to the inner end of the said shaft and being provided with openings 6Z2 whereby it may be engaged with a hooked pole, a cord or the like, and upon one side of the said arm I provide an integral weight 6Z3 while upon the other side thereof and balancing the weight cl is a weight d held on the arm (Z by means of fusible material 03 Vhen my invention is adapted to windows of the vertical moving sash type, I prefer to employ posts or stops c which serve to prevent the sash from closing the opening a and from striking the shaft 0 being preferably composed of rubber or other resilient material to take up the impact if the window sash be raised quickly or with force.

From the foregoing description, it will be seen that the arm cl may be manipulated to bring it into the alternate position indicated or back to the position shown, the shaft 0 being correspondingly rotated and the rod or plate 0 being either lowered into a horizontal position or raised into a vertical position and thereby moving the shutter c correspondingly to close or to open the opening a either entirely or in part, thereby regulating the degree of air passing there through according to the amount of ventilation desired. However, should a fire occur within the building, and the shutter c be raised, the Weight d is released from the arm (Z which immediately assumes the position indicated in dotted lines and the shutter is closed; also, if the heat approaches the opening a and the Weight cl has not been released, the plate 0 is released from the shaft 0 because of the melting of the fusible material 0* and the shutter drops and the opening a is thus closed and prevents fire increasing drafts.

Should the fire occur upon the exterior of the building the shutter b is released because of the melting of one or both of the fusible elements 6 or b and thus an indraft of fire is prevented.

It will therefore be seen that I provide ventilating means through the window frame, as well as means for regulating the said ventilation, together with a plurality of means for closing the ventilating passage in the event of'fire, thereby confining and curbing the same.

It will. be obvious that the details of construction shown and described may be changed to accommodate my invention to different conditions and with this reservation, having fully described the invention, what I claim as new and desire to secure by Letters Patent 1. A ventilator comprising, in combination with a window frame having a cham ber above the sash runs, a plurality of louvers located in the outer wall of said chamber, a weighted shutter normally raised over but adapted to close the openings between said louvers, a second weighted shutter hinged over an opening in one of said sash runs, means for opening and closing said second shutter, comprising a shaft having a right angled projection thereon mounted to move said second shutter as said shaft is rotated, and means for automatically releasing both shutters to close their respective openings.

2. A ventilator comprising, in combination with a window frame having a chamber above the sash runs, a plurality of louvers located in the outer wall of said chamber, a Weighted shutter normally raised over but adapted to close the openings between said louvers, a second weighted shutter hinged over an opening in one of said sash runs, means for opening and closing said second shutter, comprising a shaft having a right angled project-ion thereon mounted to move said second shutter as said shaft is rotated, and thermally released means for releasing said shutters.

3. A ventilator comprising, in combination with a window frame having a chamber above the sash runs, a plurality of louvers located in the outer wall of said chamber, a weighted shutter normally raised over but adapted to close the openings between said louvers, a second weighted shutter hinged over an opening in one of said sash runs, means for opening and closing said second shutter, comprising a shaft having a right angled projection thereon mounted to move said second shutter as said shaft is rotated, means for thermally releasing said first shutter, a counterbalanced arm for operating said shaft, said arm being adapted to be thermally unbalanced.

4:. A Ventilator comprising, in combination with a window frame having a chamber above the sash runs, a plurality of louvers located in the outer wall of said chamber, a deflector plate located in front of said louvers, a weighted shutter normally raised over but adapted to close the openings between said louvers, a second weighted shutter hinged over an opening in one of said sash runs, means for opening and closing said second shutter, comprising a shaft having a right angled projection thereon mounted to move said second shutter as said shaft is rotated, and means for automatically releasing both shutters to close their respective openings.

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this 25th day of September 1908.

GEORGE KABURECK.
